WLAN (Wireless Local Area Network)

This is a group of computers and other devices connected wirelessly in a

small area. A wireless network is referred to as LAN or WLAN.

WPA (Wi-Fi Protected Access)

Wi-Fi Protected Access (WPA) is an improved security system for 802.11. It is

part of the 802.11i draft security standard. WPA encompasses TKIP (Temporal

Key Integrity Protocol) along with MIC (Message Integrity Check) and other

fixes to WEP such as Weak IV (Initialization Vector) filtering and Random IV

generation. TKIP uses 802.1x to deploy and change temporary keys as

opposed to static WEP keys once used in the past. It is a significant

improvement over WEP. WPA is part of a complete security solution. WPA also

requires authentication servers in enterprise security solutions.

Requirements

(1) A WPA compatible Access Point or Wireless router, (2) Operating system updates

that support WPA. In XP, an updated Windows Zero Config service is needed. Users
